Have a professional security tech check your car for a tracking device. If you shared a phone plan, she could be tracking you through your phone. If so, you can use the account to track HER! Good luck-and don't do anything by yourself again, and you have to contact police where you live/work. The jurisdiction will be where your work is located. Call that police department and tell them and give them Detectives name that worked your original case. I'm wishing you all the luck they catch your sociopath of a wife.
